S&M BMX MAD DOG FRAME FOR 22″ WHEELS

Product Overview

The S&M BMX Mad Dog Frame is Chris "Mad Dog" Moeller's signature 22″ wheel frame designed for trail riding and racing with modern components. Built around disc brake compatibility, a tall standover, and a lightweight chromoly construction, this frame bridges classic BMX geometry with current wheel and brake standards. The 14.15″ rear end and 74.25° head angle provide stable, predictable handling on trails, jumps, and race tracks.

Key Features

• 22″ wheel compatibility – Designed specifically for 22″ wheels with clearance for tires up to 22x2.35″, offering improved rollover and speed compared to 20″ setups while maintaining BMX handling characteristics
• Disc brake mount (120mm/140mm rotor compatible) – Features IS mount spacing designed for 120mm rotors with 0mm IS-to-post adapter or 140mm rotors with 20mm adapter; provides reliable stopping power in all conditions
• 5″ tall integrated Campy-style head tube – Extended head tube height accommodates taller riders and provides additional standover clearance for aggressive trail and race riding
• 14.15″ rear end with 110mm dropout spacing – Short backend delivers quick handling while standard 110mm BMX hub spacing ensures compatibility with most BMX hubs (Profile or similar narrow-flange hubs recommended for spoke/caliper clearance)
• T-slotted seat tube for 28.6mm clamps – Accepts traditional or quick-release 28.6mm seatpost clamps for secure, tool-free height adjustment
• Heat-treated 4130 chromoly construction – Full chromoly frame built to handle trail abuse and racing impacts while keeping weight at 5.1 lb
• Custom Mad Dog details – Engraved shield on head tube, engraved '87' on BB shell, and Mad Dog tag on seat tube commemorate Chris Moeller's legacy

Compatibility and Ideal Use Cases

This frame fits 3/8″ (10mm) axles with 110mm spacing, mid bottom brackets, integrated headsets, and 1″ seatposts with 28.6mm external clamps. The disc brake mount requires IS-to-post adapters depending on rotor size. For optimal spoke-to-caliper clearance, narrow-flange hubs like Profile are recommended. Maximum sprocket size is 36T when maintaining proper chain alignment. The Mad Dog is built for trail riders and racers who want the speed and rollover advantages of 22″ wheels with modern disc braking and classic BMX geometry. Best suited for riders who session trails, pump tracks, and race courses where bigger wheels and reliable braking improve performance.
